Summary: The meta-analysis found a positive association between long-term exposure to outdoor air pollution and COVID-19 incidence and mortality. Short-term exposure to air pollutants was also positively associated with COVID-19 incidence. Reducing pollutant levels may help alleviate the burden of the pandemic.

Summary: Mercury usage in Artisanal Small Scale Gold Mining is a significant contributor to mercury contamination in the environment. This study establishes the pools and fluxes of mercury in Ghana, a country with a large small scale gold mining sector, by estimating mercury losses, deposition using a global long-range transport model, and measuring mercury levels in soils and water. The study also develops a model to assess regional increases in soil and water concentrations due to human activities and simulates future scenarios. The model shows that anthropogenic sources contribute to a 22% increase in soil concentrations.

Summary: A simple modeling approach was proposed to simulate the diurnal variations in formaldehyde concentration in ambient air. The results showed good agreement with experimental data on fine days, but had limited predictive ability on rainy, foggy, and heavily cloudy days. This study contributes to evaluating pollution levels of formaldehyde and understanding the impact of increasing methane levels on global warming and atmospheric formaldehyde levels.

Summary: During the 2022 Beijing Olympic Winter Games, atmospheric mercury levels in Beijing were monitored. The main sources were found to be central/southeastern Hebei, Tianjin, and southern Beijing. The risk from particulate bound mercury was higher than gaseous elemental mercury, and children were more sensitive to mercury exposure.

Summary: The Hg research community needs more accurate methods for measuring atmospheric Hg concentrations and chemistry. The Reactive Mercury Active System (RMAS) was used to determine RM, gaseous oxidized mercury, and PBM concentrations and chemistry. The study found that particulate-bound Hg was dominant in Atlanta, N and S Hg-II compounds were primarily present in Great Salt Lake, halogenated compounds were lowest when air was derived from the Midwest in Guadalupe Mountains National Park, and halogenated compounds were primarily present with some N, S, and organic Hg-II compounds potentially associated with biological activity in Amsterdam Island, Southern Indian Ocean. The GEOS-Chem model was used to predict measurements at five field sites, and the results showed some differences between the model values and observations.

Summary: This study did not find consistent evidence of associations between PM and O-3 and stillbirths in Sydney, Australia. However, there was potential effect modification of the association between PM10 and O-3 by maternal age. More high quality birth cohort studies are required to clarify associations between air pollution and stillbirths.

Summary: Research on the correlation between COVID-19 and air pollution has attracted attention. However, predicting ambient air pollutant concentration during COVID-19 is still in its early stages. This study proposes an improved transfer learning model combined with machine learning for accurate prediction of APCP during COVID-19.

Summary: The impact of metals contamination on pathogens and antibiotic resistance genes (ARGs) in agricultural soils and their sensitivity to ongoing climate changes are not well understood. This study found that mercury (Hg) contamination significantly influenced the distribution of soil pathogens and ARGs under different CO2 concentrations.

Summary: The study found a certain degree of correlation between short-term ambient PM2.5 levels and personal PM2.5 levels. The correlation was higher in summer compared to winter, and higher in Canada compared to the USA and China, as well as stronger in urban areas compared to suburban areas.

Summary: The increased levels of ambient air pollution in Delhi are hazardous to human health and a matter of concern for policymakers. To develop effective regulatory policies, it is necessary to gain a better understanding of the regional background concentrations of pollutants. In this study, a method is proposed to estimate the regional background concentration for the Delhi NCT region using meteorological filtering and statistical techniques.

Summary: This study found that exposure to air pollutants is associated with an increased risk of gestational hypertension (GH). In particular, exposure to PM2.5 and SO2 during the three months before conception and early pregnancy increases the risk of GH. The study also found that during periods of severe air pollution, older women and those exposed to higher temperatures have a higher risk of GH related to PM2.5 and SO2. Overall, improving air quality is crucial for public health, especially for sensitive populations like pregnant women.
